Application filed November 1921. Serial No. 512.583.

' Forest Park, in the county of Cook and State of Illinois, have invented certain new and useful Impfrovements in'Dimm'ers for Automobile-Headlights; and I do declare. the following to be a full, clear, and exact description of the invention,such as will enable others skilled in theart to which it ap-. pertains, to make and use the same.

This invention relates to an improved attachment for automobile headlights which serves to dim the light and to eliminate the undesirable glare which is so troublesome and dangerous to drivers of approaching machines.

The principal object of the invention is to provide a simple and inexpensive attachment which is capable of being applied on the exterior of the headlight, this attachment being held in place by tyin means, thus permitting it to be easily an readily applied or removed whenever necessary or desired.

More specifically speaking, it is another object of the invention to provide a dimmer which is in theform of a strip of semitransparent .fabric which is placed over the exterior of the lens at the center of the same 1 seats to eliminate the undesirable glare at this point, this fabric having an elastic retaining elementf' associated therewith for holding it in position onthe light and the 'abric being so constructed as to-permit it to be effectively applied on all sizes of head; 1i hts.

Other objects and: advantages of the invention will be apparent during the course of the following; description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the .same: 1 I

Figure 1 is a side elevational view of a conventional form of headlight with my improved dimmer attached thereto showing clearly the manner fit the light.

Figure 2 is a front elevational-view of the headlight showing the position ,of the attachment more clearly. 1

Figure-3 .is 'a detail perspective'view of of adjusting" the same to the attachment removed from the light.

Figure 4 is a detail section taken'sub- 's'mall brass rings 5 holes 4land the free ends stantially on the plane of the line 4-4 of Fig. 1.

s previously suggested, the improved dimmer is in the form of a semi-transparent elongated strip of comparatively heavy or thick fabric 1 which is adapted to be disposed horizontally across the exterior of. the central portion of a headlight lens L,'this strip being of a length to permit its ends to be extended over the lens holding'rim R and beyond same so that they terminate adj acept the forward end of the body B. When placing the attachment on the light, it is arranged directly in front of the bulb so as to affect .the extremely undesirable rays which issue from this point and to modify and dull the lightto a considerable degree. By carefully examining the dimmer it will be seen that the edges of the fabric are folded over and stitched as indicated at the point 2- and one end is doubled upon itself and stitched to form what may be conveniently termed a. pocket 3. At its opposite end, the fabric is formed with a plurality of rows of alined openings 4 which serve a purpose to'be hereinafter described and the edges of these openings are reinforced by ,or the like which are attached to the fabric in any suitable way.

These rows ofholes constitute av mea'iis whereb the attachment can applied on different sizes of headlights. For the purposeof holding the fabric 1n position on the, light, I make useof a yieldable retaining element 6 which is preferably composed of some elastic material. This retaining element is held in the aforesaid .pocket 3.

-In'use, the strip of fabric 1 is stretched across the central portion of the headlight lens as shown in the drawings and the ends thereof are drawn over the retaining rim R. Then, the elastic retaining'element 6, which has previously been placed in the pocket 3, is passed around 'the body of the light as indicated in the drawings and one end thereof laced through the proper row of some headlights, the outermost row' of holes will be used and on others the innermost row would probably -be-selected. If the last DHJIIGd'I'OW of holes should be selected, there would be a portion of the fabric left free. to wave. about. It is desired to eliminate this. Therefore, this surplus portion of material is folded upon itself and the'outermost row be effectively tied together; On

of openings is alined, with the innermost row so that the retaining element can be laced through both rows to hold the surplus material in this folded state. The manner of accomplishingthis is indicated in the drawings. The manner suggested of taking care of this surplus material need not of course be followed, because in some instances,

this surplus material could be entirely cut off after the attachment is Once adjusted to properly fit a particular headlight. also unnecessary to untie the ends of the elastic retaining element 6 because this can be simply slipped over the retaining rim in removing and applying the attachment.

1 claim:

Adimmer for automobile headlights com I prising an elongated relatively narrow strip Itis alacca of semi-transparent fabric material adapted for horizontal disposition across the central exterior of the headlight lens, the opposite ends of said strip being intended to be drawn over. and beyond the usual clamping rim,

one of the ends bf said strip of fabric being formed with a plurality of spaced vertical rows of holes, the alined with one, another, and a flexible re-, taining element connected to one end of said strip, said element being intended to be laced through a selectedrow of holes and tied to hold the dimmer inoperative position on the light.

In testlmony whereof I have hereunto set my hand.
